Steel Pipe Fittings Concentric Reducer 3X4inch SCH40 ANSI B 16.9 Butt Weld Pipe Fitting


The reducer is a joint used to connect pipelines in thermal insulation steel pipe projects, which is also known as a reducing joint. When the nominal diameters of the pipes that need to be connected in the renovation or new pipe network are inconsistent, it is necessary to use the commonly known "big and small ends" to connect them. The big and small ends can be divided into two types: concentric reducing and eccentric reducing. After connecting the pipes with concentric reducing, the center of the circle is in a straight line, and after connecting the pipes with eccentric reducing, the center of the circle is not in a straight line.
